Your best bet is through a company. If you have a reasonable job opportunity, familiarise yourself with the work visa and residency procedures. Your future employer will likely help you in the process.
However, the economy currently is tough also in the EU, so you’ll need to find a niche.
As a vetted german beer enthusiast, may I say that the big-brand beers are on average as good (or bad) as the american beers I know. Differences imho originate from drinking preferences (light beers) and allowed ingredients or additives, but that has a minor impact on sensory quality. Personally I often missed aroma and bitterness (hops) and gravity of most beers I tried in the USA, but that‘s just me.
